"Everything went smoothly. The cells arrived on time. The BMS and displays did too. I highly recommend this seller. They were reliable and helpful at all times, providing updates on the delivery. The cells are genuine. They even took time out of their own day to send the order."

"The order arrived about 70 days after shipping. The BMS was already installed in the box and assembling the cells was really easy. In two hours everything was assembled, tested, and working. It's been about two months now and everything is working perfectly. I'm very satisfied."
